The heart of this Infiniti Q70 is the 5.6-liter VK56VD V8 engine. This naturally aspirated powerplant is renowned for its smooth power delivery and robust construction. Because the oil capacity for this engine is 6.4 quarts (with filter), selecting a fluid that maintains viscosity stability is paramount. The recommended AMSOIL Signature Series 5W-30, for instance, is designed to resist shear, ensuring the oil film remains intact even under the high thermal stress typical of a V8 engine in a luxury sedan. Using a high-quality AMSOIL Oil Filter ensures that harmful particulates are captured effectively, preventing sludge buildup that can clog oil passages and lead to premature engine wear.
Transmission and Drivetrain Protection
Power from the engine must be efficiently transferred through the transmission and to the wheels. For the automatic transmission, AMSOIL offers both Signature Series and OE formulations that meet the RE7R01A specifications required by the 7-speed unit. Whether you choose the fuel-efficient Signature Series for maximum performance or the OE version for standard protection, these fluids are designed to prevent wear and extend the life of the transmission components. They remain fluid in sub-zero temperatures and provide the necessary lubrication for heavy towing or challenging terrain.
For the differential and transfer case, the lubrication requirements are specific. The front differential requires 1.4 pints of 80W-90 GL-5 fluid, while the rear differential, which requires synthetic oil, holds 2.2 pints of 75W-90. The rear axle of this Infiniti is a critical area where synthetic gear lube excels. AMSOIL’s SEVERE GEAR and Long Life gear lubes are formulated to control thermal runaway, protect against rust and corrosion, and reduce operating temperatures. The Long Life variant, specifically the 75W-90 formulation, is engineered for extended service intervals, making it an excellent choice for maintaining the drivetrain’s smooth operation over the long term.
Fluids for Cooling and Safety
Maintaining the cooling system is just as vital as the engine oil. The 2016 Infiniti Q70 requires 11.5 quarts of antifreeze. AMSOIL offers a pre-mixed Passenger Car & Light Truck Antifreeze & Coolant that exceeds original equipment manufacturer (OEM) requirements. This formulation protects against corrosion and erosion, ensuring the engine does not overheat even under severe driving conditions. Additionally, for the hydraulic brake system, AMSOIL’s DOT 3 and DOT 4 Synthetic Brake Fluid provides a stable viscosity over a wide temperature range. This stability is crucial for maintaining consistent braking performance and protecting the ABS system from moisture-induced corrosion, which can lead to costly repairs.
Additional Maintenance Products
Beyond the essential fluids, there are several other products that can aid in the preservation of your vehicle. The AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid is recommended to reduce friction and keep seals soft to prevent leaks. For owners looking to maximize fuel economy and engine cleanliness, AMSOIL P.i. Performance Improver Gasoline Additive can help restore up to 14% horsepower and clean fuel injectors. Furthermore, for vehicles that see seasonal storage or infrequent use, AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, preventing varnish and gum buildup that can clog the fuel system. For seasonal storage protection, AMSOIL Engine Fogging Oil is designed to protect internal engine components during long periods of inactivity.
